-FACTURING COMPANY, Ay CORPORATION or INDIANA STANDPIPE `'CONNECTION Appncatinniea February 2, 192s. serirno. 251,296.

` This inventionrelates to improvements in standpipe connections, and more especially such a connection known as a Siamese, permitting the attachment of two hoses. My improved standpipe connection is espe cially adapted for use in connection with firefighting installations.` Buildings, especially h igh ones, frequently are provided with tire extinguishing systems, aconnection being provided at lone of the outer walls for attaching a hose yfroma re engine in order to permit'such engine lto increase the pressure or supply of the water'insid'e. My improved invention relates. to a standpipe connection of this kind permitting the attachment of two hoses.

One of the features of my-invention is the provision of such a standpipe connection that projects only a short distance from the 20. out-si de of the building in which it is installed.

This is an advantage especially in metropolitan areas where the outer wall of the building is frequently flush with the edge of the sidewalk. Y lf the standpipe connection projects '25 an undue distance over the sidewalk there is danger of injury tovpedestrlans. My vim y proved hose connection is so close to the Y building that there is little, if any, danger of the same being struck bypasserby.

Another feature of my inventionr is the housing of the Y connection inside of the wall of the building itself, thus materially reducing the distance thatl the hose connections proi ect beyond the outer surface of the wall. In connection with this feature, I provide clapper or check valves that form units with the nipples carrying the hose connections, each of such nipples with its check valve Vbeing readily removable from the Y piece from the 0 outside ofthe building without disturbing the installationof the standpipe connection.

Other features and advantages of my inf vention will appear more fully vas I proceed Y lwith my specilication, I 1 Inv that form of device embodying the features of my invention shown in the accompanying drawings, Figure 1 is a view in front elevation. Fig. 2 is a View taken as indicated Bodypart 10`is lpreferably put inthe wall ior by the lineQ of Fig. 1, Fig. 3 is a view taken as indicated by the line 3 of Fig. 2, Fig. 4 isa trance of foreign matter.

View taken as indicated by the line 4 of Fig. 2, andFig. is aview takenas indicated Vby the line. 5 of Fig. 1'. I

As shownin the drawings, my fimproved standpipe connection comprisesv a Y body piece indicated by 10 which is adapted to be inserted in the wall 11 of the building preferably while such` wall is in process of A construction. The body piece 10 is provided-on.

its inner face with a threaded hole adapted j to receive the pipelQleading to the standpipe or other water piping in the building; and the outer face of the body part 10 is provided with two threaded vopenings 13 adapted to receive the nipples 14.

Each of the nipples 14 carries at its inner end a clapper or check valve 15 hinged at its upper edge as indicated by 16. The valve 15 is small enoughto pass through the opening 13 when the nipple 14 is screwed out from the outside.

17 indicates a face plate provided with holes registering with the holes 13 through which the nipples 14 are inserted. The face plate 17 is here shown substantially rectangular inshape with a depending centrally arranged tongue 17a; but Ait is obvious that this plate may be made of any suitable'shape and bear fany suitable design or configuration. For example, it may contain directions as to pressure, connections and the like.

Each of the nipples 14 is provided with a threaded locking springer collar 18 adapted to be screwed against the face plate 17 to lock the same against the flange 10a on the body part 10 surrounding the hole 13. When tightened up, the locking collar 18 serves to hold the 'face plate in position and also servesA to hold the nipple tightly in place. l

' The outer 'end of each of the nipples-14 is vprovided/with the usual internally threaded swivel 19 for attachmentto a hose. E20 indi Cates" the` customary cap to prevent th'e 'len'- In7 Fig. 5 thereA is shown proj ecting through the depending tonguela ajwate'r supply pipe. 21 having on its outer end the usual faucet 22. In installing thel standpipe connection 'the during-the building. After the', building 'laA sov

entirely completed the face plate 17. is then put into position, the nipples 14 with theA valves 15 inserted and the locking collars 18 tightened up. When installed this way the .nipples and valves are free from injury during the building operation. Also, the body part 10` is comparatively simple, rugged and cheap i'n construction so that there is littl'e danger of damage to the same during the b-uildnig ot the al'so, it lost or stolen. the loss is relativelyslght. y

By using a tace plate 17 which is installed Y the last thing, the joint between the con-nec` tion and the masonry work `of the wall is entirely concealed.

While I have shown and described certain Vembodiments of my invention, it is to be unl the outer side of said bodyl piece adapted to liel substantially flush with the outer Surface Ofsaid wall and provided with a plurality of threaded openings a face plate provided? with a plurality of holes registering with said last mentioned openings, said tace plate provided witha marginal flange adapted to lie outside otf said wall and cover the edge of the wall adjacent said body piece; nipples with exteragainst the marginal edge of' the tace' plate surrounding the holes therein to grip said facie plate between said lockin-grings and the flanges surrounding thefopenings in the outer side ofthe body piece.

combination with a wall of a building; a body piece built into said wall, said body piece an opening adapted to receive a pipe connection from the building, and a plurality of threaded openings in its outer side accessible from the outside ofthe building; a face plate provided with, holes registering with said' last .mentioned holes, said face plate lying outside the wall of the' building and having a marginal edge extending over the edge ot' the wall adjacent the body piece ;v nipples with external threads inserted through the holes in the tace plate and screwed into the threaded openings in the outer side of the body piece; and `locking rings on said nipples lying outside of the tace plate and screwed against the marginal edges of said face plate surrounding the openings therein to hold' said tace plate in position against said wall.

In Witness whereof, I have hereunto set nly hand this 30th day of January, 1928.
